python - 连接被对方拒绝 : 10061: No connection could be made because the target machine actively refused it

我的步骤:

构建镜像 docker build . -t scrapy

运行容器 docker run -it -p 8050:8050 --rm scrapy

在容器中运行scrapy 项目:scrapy crawl foobar -o allobjects.json

这在本地有效，但在我的生产服务器上出现错误:

[scrapy.downloadermiddlewares.retry] DEBUG: Retrying <GET https://www.example.com via http://localhost:8050/execute> (failed 1 times): Connection was refused by other side: 10061: No connection could be made because the target machine actively refused it..

注意:我没有使用 Docker Desktop，我也不能在这台服务器上使用。

我错过了什么？
我已经在这里检查过:

Scrapy, Splash and Connection was refused by other side: 10061

Scrapy + Splash = Connection Refused

在 Windows 防火墙中，我为入站和出站允许端口“80,443,8050”(用于域/私有(private)/公共(public))创建了新的 TCP 端口规则
然后重试在我的容器中运行 C:\root\scrapy>scrapy foobar -o allobjects.json，但仍然收到“连接被拒绝”错误。
我运行了这些命令:

在我的容器中:C:\root\scrapy>netstat -a

在我的主机操作系统上:D:\Progams\netstat -a

在这两个输出中都没有显示端口 8050...但我原以为它会在那里？

基于@LSerni/@Pankaj 关于 Splash 的建议:
我不知道在你的例子中我需要输入什么而不是 scrapinghub/splash 。
我试过:PS D:\Programs\image_addons> docker run -p 8050:8050 -p 5023:5023 scrapinghub/splash

Unable to find image 'scrapinghub/splash:latest' locally
latest: Pulling from scrapinghub/splash
docker: image operating system "linux" cannot be used on this platform.

和:PS D:\Programs\image_addons> docker run -p 8050:8050 -p 5023:5023 scrapy/splash

Unable to find image 'scrapy/splash:latest' locally
docker: Error response from daemon: pull access denied for scrapy/splash, repository does not exist or may require 'docker login': denied: requested access to the resource is denied.

从我的帖子中可以看出，Splash 通过我的 Docker 文件安装到我的 scrapy 镜像中，那么我需要如何启动它？

基于@Thiago Curvelo 对 Splash 的评论:
因此，在本地 Windows 10 和 Docker 桌面上，上述设置适用于我，我没有(至少没有明确地)启动单独的 Splash 实例，但也许这是 Docker 桌面中的逻辑构建？在我的服务器上，我无法使用 Docker Desktop，因为它不支持 Hyper-V。
如果您查看我的 Dockerfile，您会看到我将 scrapy-splash 安装到我的镜像中。
现在谈谈您的观点:显然我需要单独启动一个 Splash 实例？
该容器是否必须与我的 scrapy 容器分开并并行运行？或者可以(并且应该？)我将 Splash 图像添加到我现有的 scrapy 图像并基于它运行一个容器？我是新手，所以不确定这是否是我应该在谷歌上搜索的内容。
(我只是在尝试 scrapy/splash ，因为我认为 scrapinghub 部分可能指的是图像名称，在我的情况下 scrapy ，我猜我也错了;-))

最佳答案

你需要启动一个 Splash instance首先，让它监听 8050 端口。例如:

docker run -dit -p 8050:8050 --name my_splash scrapinghub/splash

然后，将启动 URL 设置为指向该正在运行的容器:
设置.py:

SPLASH_URL = 'http://my_splash:8050/'

最后，启动 Scrapy 容器，将其链接到 Splash 容器:

docker run -it --link my_splash --rm scrapy

这样你就可以将 Scrapy 的请求发送到 Splash。
